1 Claim.

This invention relates to combs having locking teeth for the purpose oflocking the comb in the hair.

Objects of the invention include the provision of a comb having a hollowback and a series of conventional spaced fixed teeth extendingtherefrom, rotatable blade-like teeth located between pairs of iixedteeth, and means in the hollow back for rotating said teeth betweenpositions parallel with the xed teeth and at an angle thereto for thepurpose of locking strands of hair between the fixed and rotating teeth.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 isa view in elevation showing a comb according to the invention, partsbeing in section;

Fig. 2 is a fragmentary view similar to Fig. 1 but showing the rotatingteeth in hair-locking condition;

Fig. 3 is a section on line 3-3 of Fig. 1;

Fig. 4 is a View similar to Fig. 3 but showing the rotatable teeth in adifferent angular position;

Fig. 5 is a section on line 5-5 of Fig. 2; and

Fig. 6 is a section on line 6-6 of Fig. 1.

As shown in Fig. 1, there is provided a comb .I0 having a back I2, saidback I2 having a series of spaced teeth I4 extending therefrom, the backbeing provided with an elongated chamber I6 therein. Between each xedtooth I4 there is provided a circular opening leading between thechamber I6 and the spaces between the roots of teeth I4. Each openingrotatably receives a pin to which is secured a blade-like tooth 20, eachtooth 20 having a width similar to thewidths of teeth I4, but the teeth20 are rectangular in outline as sown in Fig. 2 so that when rotated onpins I8 to the Fig. 2 position, teeth 20 substantially fill the spacesbetween teeth I4. However, when the teeth 20 are rotated 90 from theFig. 2 position, they lie parallel with teeth I4 as shown in Fig. 1 andFig. 6.

Each pin I8 is secured to an element 22 in the chamber I6. Theseelements are each provided with an eccentric pin 24 secured to alongitudinally movable bar 26 so that as the bar is longitudinallymoved, it will swing elements 22, thereby rotating teeth 20 thru anangle of 90 between the positions of Fig. 1 and Fig. 2, that is, betweena position wherein the teeth are all parallel as in Fig. 6 to a positionwherein alternate teeth are arranged at right angles as shown in Fig. 5.

The bar 26 is provided with a slot receiving a stem 28 of a ngerpiece30, arranged for moving the bar 2E longitudinally in the chamber I6.

It will be seen that this invention provides a comb having rotatablelocking teeth for locking in the hair in an eicient manner so that thecomb cannot fall out of the hair and so that the hair is firmly lockedby the comb.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claim, but what I claim is:

A comb having a back, a chamber therein, a series of xed teeth extendingfrom the back, a rotatable blade-like tooth between each pair of fixedteeth, an eccentric for each rotatable tooth, said eccentrics beinglocated in the chamber, a bar secured to each eccentric, and means formoving the bar for rotating the eccentrics and therefore the rotatableteeth.
